Fatality Trends
Pedestrian Master Plan 2010
▰ Vision: For Louisville to become the safest and most
appealing community for pedestrians!
▰ Mission: Create a community wide culture that
supports pedestrians through physical improvements, policies and pedestrian programs by increasing the pedestrian system network while simultaneously reducing the rate of pedestrian crashes.
Understanding Pedestrian Crashes
▰ 23% of fatalities occurring on Metro
roadways were pedestrian fatalities.
▰ Louisville conducted a 5-year pedestrian
crash analysis to identify:
▰ Trends ▰ High risk populations ▰ High crash locations

Vision Zero
▰ aka: Safe Systems Approach ▰ Principles: ▰ People make mistakes ▰ Crashes are going to happen ▰ The human body can only tolerate a certain amount of crash force
Vision Zero
▰ Why? ▰ Average Crash Costs in KY: ▰ Fatal Crash = $9,281,571 ▰ Serious Injury = $537,913 ▰ Societal Costs: ▰ US: $433.7 Billion (Source: National Safety Council) ▰ KY: $8.9 Billion
Vision Zero
▰ Paradigm Shift: ▰ Let’s not focus on eliminating crashes ▰ Let’s focus on eliminating fatalities and serious injuries
Vision Zero
▰ How? ▰ Other elements of the Safety Systems approach: ▰ We can’t continue to blame the driver ▰ Shared responsibility ▰ Proven solutions ▰ Proactive approach (treat the risk factors)
Shared Responsibility?
▰ The Swiss Cheese Model: ▰Layered security measures are
represented as slices of swiss cheese with the holes being weaknesses in the parts of the system
▰A “failure” only results when a hole
in each slice momentarily aligns, permitting a hazard to pass through all of the slices
The Swiss Cheese Model was originally put forward by Dante Orlandella and James T. Reason of the University of Manchester
Vision Zero
▰ “Safe Systems” Goal: ▰ ensure redundancy in the system so that
when a crash does happen, the crash forces released are within the boundaries of human tolerance and that no fatalities should occur and serious injuries are reduced

Vision Zero
▰ Treat the risk factors? ▰ Improve the roadway features with high
correlation to fatal & serious injury crashes
▰ How are risk factors determined? ▰ In-depth Safety Diagnosis
(aka Analysis of Crash & Roadway data)
